Application filed March 9, 1907. Serial No. 361,482.

To all whom it "my concern:

Be it known that I, HERBERT H. STEELE, citizen of the United States, and resident of 1 Syracuse, in the county of Onondaga and State of New York, have invented certain 5 new and useful Improvements in Type I-Vriti Machines, of which the following is a speci cation.

My invention relates to ribbon feeding mechanism of that class of typewriting machines wherein the ribbon has connections with the means for drivin or im 11in the carria e. In machines of this c as w en- 1 ever the carria e is freed or released from its escapement devices either by actuating a tabulator key or otherwise, and is drawn 3 varying distances by the carriage impelling 1 device (usually a. spring drum), the ribbon, Y which has connections with the carriage im- 3 polling device will usually be fed correspond- 1 mg distances. Durin this feed of the ribbon the printing devices are inactive and I consequently a portion or section of the i ribbon will pass the printing point without receiving impressions from the types, this portion or section varying in length with f the distance which the carriage jum s or is drawn continuously when release from the esca ment devices. The result is that 5 as the ribbon becomes more and more ex- 5 hausted in use, these unused portions or sections of the ribbon will become more and rinting executed by the machine, some of e characters be ing much darker than others and the typewriting consequently having an uneven, patchy appearance. Moreover, in machines of the character referred to and in which the direction of the longitudinal feed of the ribbon is automatically reversed, it sometimes I happens that the end of the ribbon is-reached i dun w one of the jumps of the can'iage, with iihe resultthat the rapid movement of i the carriage preventsthe eflective working i of the reversing mechanism and the feed 0 g the ribbon is arrested or else the ribbon is The main object of the present invention is to overcome these and similar defects.

To the above and other ends the v invention consists in thefeatures of construction, combinations of devices and arrangements of arts-hereinafter described and particudicated by dott lines.

Figs. 8, 9, 10 and 11 are onlarged diagrammatic views taken on the plane represented by the line y-y of Fig. 5 and looking in the direction of the arrows at said line, the said views showing difl'erepfpositions of two cooperative parts here' er referred to as a releasing lever and a disconnecting or shifting member. Figs. i2 and 13 are views showing 1n top plan and on an em larged scale, difi'erent ositions of the spring plunger and detentw ieh aid inpositioning the ribbon driving shaft. Fig. 14 is a disgrammatic top plan view of the ribbon feed.- mg and ribbon reversing mechanisms. Figs. 15 and 16 are diagrammatic vertical sectional views further illustrating the ribbon feeding and ribbon reversing mechanisms.

Referring first to h3g3. I to 3 inclusive of the drawings, the main frame of the machine is shown as comprising a base 1, corner posts 2 and a top late 3. Key lovers 4. are-fulcrumed on a ulcrum plate 5 in the rear of the base, each key lever beingprov'ldedwithiaa restorin spring 6 and-having pivote'dftoitnt 7 asubever 8, thelowerarm whereofcobpe-J erateswith s fixed abutment 9 and the upper.-

The type bars are arranged in on said type burs cooperate with frame. The construction is such that when the universal bar is operated the vibrator 42 is caused to more upwardly to intcrpose the ribbon between the platen and the tvpc on the actuated type bar. Each ribbon spool disposed shaft 46 having a lixcd bearing 49. llXtfl to the lower end of each vertical sha ft 4S is :1 small beveled gear 50 which meshes g with a beveled pinion 51 fixed at the forward 1 end of a horizontal and reorwerdlv extending bottom which receive 3 A carriage feed rack '31 is secured at the free ends of rearwzirdly extending arms 22,

the latter being pivoted at 22 16 of the pluten carriage. A spring 2-1, like that shown or of any tion, may be employed to nmintuin the feed rack normally in engagement with a feed pinion 25 fixed to the forward end of :1 short l to the side bars 1 other suitable construcshaft,- 26 hearing in a bracket 27 fixed to the top plate is operatively connected with the rear end of the shaft 26 and cooperates \vith'escapeinent A toothed escapement wheel 28 dogs 29 mounted on a dog carrier or rocker 30 which is pivoted on :1 to and de nding from the top plate. rocker 30 bracket 31 d The as :1 horizontally disposed arm 30" 1 which is connected hr a link 3?. with an arm 33 of a universal bar frame, which latter comrises also a rock proper 35, the latter extending? from side to side of the machine beneath te key levers. A carriage impelling device or s 36 is rotatably mounted on a stu 37 secured to the bracket 31 and is connected b\' a band or strap 38 with a pin 39 depending from the rear bar of the carriage.

shaft 52 having hearings in lugs 53 dependim from the top plate. Fixed to the rear end (if each shaft 52 is a beveled pinion 54 and adapted to cooperate therewith is a beveled driving pinion 55 which is fixedly secured on a driving or power shaft 56. said shaft. as best shown in Fig. 4, extending from side to side of the machine beneath the to) plattand being slidnbl mounted in fixed hearing; lugs 57 depending from the top plate. Mounted in front of and o-axially with the spring drum 36 is a beveled )inion 58 which is adopted to be turned with said sprint drum during the left-hand rotations of tlrc latter, the connection between the spring' drum and the pinion 58 for effecting t-lns resnlt not beins shown. The beveled pinion 5S meshes constantly with a. beveled pinion 59 which is mounted on the driving shaft 56. The connection between the pinion 59 and the driving shaft 56 is best illustmted in Figs.

1 4 and 5 and may be brieflv described. The

shaft 34 and a universal bar I sion 60 pro the flange 61 ring drum 1 pinion 59 has 11 rightward collar-like extended with two flanges 61 and 62. being but a short distance from the union proper 59. An angled sheet meta arm 63 is secured at one end to the Acting through the '1 strap 38 the spring drum tends constantly to draw the carriage leftward acres the top I plate and when any key lever 4 or the space or (not shown) is operated, the universal her 35 is actuated, causing bottom of the left--hnnd lug 57 bv a headed screw 64, said arm at its inner endheing bent upwardl at ri' ht angles and bifurcated to form a. ork. he prongs 65 of the fork or bifurcated portion of the arm 63 loosely omhrnce the extension 60 between the flange 61 and the hack of the pinion 59, the const methe esc-u-peinent devices above described to cooperate m n 1 known manner to permit drawn a. letter space distance townrt by the spring drum.

An in ribbon 40 is wound upon, and has its ends attached to, ribbon spools 41 mounted above the top plate one at each side of the machine and forward of the platen. In passthe carria e to be the left,

; posed notches which receive fingers 66 tion being such that while said pinion may turn freely it is revented from moving lengthwise of the s aft- 56 b the prongs 65. The flange 62 is formed wit oppositely disroj ectin leftward from a. collar 67 secured y a ing from one spool to the other the ribbon co- 5 o crates with a ribbon carrier or vibrator 42 w ch IS arranged centrally of the machine 1 66 may move lengthwise when the driving and is supported on a guide bracket 43 to the top plate. The lower end of the ri bon carrier 42 is pivotally connected with the forward arm of a horizontally operatj lever 44 fulcrumed at 45ml lug 46 defixed i shaft is moved len l the flange 62 or t 10 headed screw 68 to the driving shaft 56. 'l he collar 67 turns always with the driving shaft and throu h the fingers 66 causes the flange 62, as wclfos the extension 60 and pinion 59 to turn, while at. the some time said fingers hwise without afiecting pinion 59. It 15 not thought necessary to describe the connections of the pinions 58 and 59 with the spring drumand-driving shaft at greater length as the connections shown do not differ essentmlly from those em loyed in the Monarch typewriter, and, 0,5 9.1 as my invention is eoncerned, said connections may be of any suitable sort. It will be understand that rolary motion is eonnnunit-atoll from the s wring drum to the driving shaft 56 through the pinion 59 and that endwise to and fro movements of said driving shaft may he eft'erted without. all'eeting the pinion :39. it will further be nnderstoml that earh ribbon spool 41 is connected thron 'h a trainer mechanism, sueh as has heen di'serihed, with a beveled pinion 54 and that the beveled driving pimons 55 are so arranged upon the driving shaft 56 that only one of said driving: pinions is engaged at a time with its associate a pinion 54. In order to reuse the rihhonto wind from one spool to the other and vice versa the driving: shalt may be moved back and forth endwise to ell'ee-t the alternate en gagement of the driving linions 53 with their respective associate pinions 54. This endwise movement of the shaft .36 may be ae emnplished manually but it preferably is also effected automatically by anv suitable r means, such, for-example, as that shown in the liniied States patent to Felhel and Gabrielson, No. 703.339, dated June 24th, 1902.

To avoid complirating the drawings the ribbon reversing mechanism of the patent 2 above referred to has been illustrated se. f aratelv from the other devices and will lie found tliagrammark-ally shown in Figs. 14, t5 and 16 which will now be briefly described, said patent being available for a fuller deseription. V elusive. its designates an elbow lever pivoted to the under side of the left-hand ribbon spool ll and retained for the greater part of the time in the position shown in Fig. by folds of the ribbon 40, which with the driving shaft 56 positioned as shown in Fig. 24., is being wound off the left-hand spool i and on the right-hand s )ooL- Until the? leftdiand spool is emptied the horizontal arm 1 of the elbow lever 48" serves to retain in inoperative position a ram plate 49' slidably secured to the under side of the spool 4!. 1 Ti hen the ribbon has been completely unwound from the SJOOl it will release the up 7 right arm of the el ow lever 48', thereby per milling the cam plate to drop vertically; downward to the position shonn in Fig. 16 in which position the cam surface 50 is adapted to engage with an upright pin 51 secured at one end of a l'iorizontal s .1ring pressed lever 52 the other end whereof nor- 1 mall contacts with and presses rearwardly the. upright arm 53' of a sprimvpressed slide f rod 54'. The rear end of said slide rod is bent laterally and forwardlr, terminating in i a trip pin 55' which normally is out of mesh with a worm 56 fixedly. secured to the drivi ing shaft 56. As the l'lbbull'SPOOlPUllllIlUGS to rotate after the cam late 495 has dropped toop eretwe position, t to earn face 59', actmg upon the pin 51, cams the horizontal l deferring to Figs. 14 to 16 inlever 52' against the pressure of its spring :32" to the position shown in Fig. 1-1, thereby allowing the slide rod 5-4 to be moved for-- ward by its spring 54" until the trip )ll] 55 engages with the worm 56'.

ga ement takes plat-e the driving shall 56. as it. is rotated during the letter spat-e feeding, movements of the carriage, will be wormed along in the direetion of the arrow in Fig. H- unt-il the left-hand driving pinion 55 meshes with its assoeiate pinion 54 and the corresponding right-hand pinionsdisengage, thereby reversing the direction of the longitudinal feeding movement of the ribbon. -\s the ribbon begins to wind hack on the left-hand spool it will press the upright arm of the elbow level 4 against the spool ('UI'Q. restoring said lever and with it the ram plate -'!'l' to the position indicated in Fig. 15. When the earn plate 49' is moved upward it releases the horizontal lever 52'. permitting: the latter to again art upon the slide rod 54 to push said slide rod rearwardlv and to restore the trip pin 55' to nmrworlting position, the spring 52 being strong enough to overcome the spring 54". It will be understood that the right-hand ribbon spool is provided with a similar train of reversing: mechanism which will 0 wrote in a manner similar to that just deserilied when the righthand spool is emptied of the ribbon.

The driving shaft 56 is provided with a circumferential groove 69 whieh is engaged by a notched extension 70 which, as e early shown in Fig. I, is formed at the forward end of a horizontally disposed detent arm TI. the latter at its rear end can-ring an upwardly pro ecting pivot pin 72 which engages in a i bearing block 73 extending horizontally forward finm the bracket 31. The arm 71 also carries a detent roller 74 which eoi'iperates with notches 75 and 76 formed in the head 7? of a slide member, the latter also comprising a stem or plunger portion 78 which is received in a hole 79 formed in the bearing bloc i 73. A coiled spring 80 surrounds the stem of the slide member within the hole in the block 73 andtends to maintain the notched head 77 in engagement with the roller 74. The slide member and vibratory detent device or member above briefly described resemble in construction those emploved in the Monarch machine and said slide and detent device are adapted to eooperate to complete the endwise movement of the driving shaft 56 in either direction and also to im'iintain said shaftin position after such endwise movement, substantially as set forth in the patent to \i'ebb, No. 599,428, dated Februarv 22nd, 1898. Some special functions of the (latent. device and slide member in the present case will be considered later on in oonneetion. with the operation of my vimprtwemefnts.

Figs. 1 to 4 inclusive clearly illustrate a.

.ifte-r l iis enstop mem &

tabulating mechanism in connection with l which my invention is shown, said tabulating mechanism resembling generally that form- 5 ing the subject-matter of the patent to Gfl hnelson, No. TS-1,31 7, dated March 7th, 1905. g It is to be understood, however, that my ini vention mar be used in colmection with other styles of ta )ulatiug mechanism to automatically cut out or render inoperative the 11bbon feeding devices. The tahulating mechi anism shown is operated by a ta-bulating key 5 81 carried by akey lever 82 which is pivoted at 83 to a bracket 84 secured to the base of I the machine, said key lever being provided f \n'th a restoring s ring 85. The key lever i 82 carries a lateral y projecting pin 86 which 3 extends into a slot 87 formed in a sub-lever 88, the latter being pivoted at to a fixed i part of the machine. The rear end of the subever 88 is pivotallv connected with an actusting link 00 which extends upwardly from the sub-lever through an opening in the top 2 plate and is pivotally connected at its upper end with a crank arm 01, the latter being secured to the end of a rock shaft or oseillatorv stop rod 92. A spring 93 surrounds the link and, hearing at the lower end against the base of the machine and at the up er end against a collar 94 secured to the ink 90, 5 tends to restore the link and the parts con- 1 nee-ted thereto to normal position after operl ation. The stop rod or her 92 extends in the direction of travel of the carriage and is supported in ears Q5 pro'ect ing iearwardly from the standards 20. he stop rod 92 may be provided with a scale corresponding with the. usual carriage scale and the front and back sides of the bar are serrated or notched as indicated at 96 to receive detachable and adjustable sto members 97 having forwardly and upwar y projecting sto lugs 98. Secured to the rear bar 17 of t e carriage is a l rearwardly projecting stop 99 which is adapt ed to coo erat-e with the stop lugs 08 of the rs 97, said stop lugs, however, as shown in Figs. 1 and 3 being normally out of the path of movement of the carriage stop 99 and being moved into the path of said stop 99 when the key 81 is depressed. The collar E 94 on the actuating link 90 is provided with an inwardly and forwardly extending abutment or finger 100 which co-acts with the outer end portion of the lEhi-hflnd arm of a releasing lever 101 fitlcrumed at 102 to :1- lug 103 depending from the top plate. The lever 101 is provided with an upwardly extending top portion 104 which contacts with the top plate to limit the. upward motion of the right-hand arm of the lever. A forked rack lifter 105 is pivotally connected at 106 to the end portion of the inner or left-hand arm of the releasing lever 101. The rack lifter extends upwardl through an 'openin gin the top plate and 1s bifurcated to provide arms 107 embracing loosely the bracket 27, sold arms being bent horizontall forward near their upper ends to form li ting shoes 108, the latter lying beneath and normally out of contact with the teeth of the carriage rack 21. It will be understood that when the tahulating key 81 is operated it acts, through the sub-lever RS, link 90 and crank arm 91.

g on the stop bar 92, rocking the latter forwardly until the stop lugs 98 are in the path of the carriage stop 99. At the some time the finger 100 will depress the outer arm of the releasing lever 10] and lift the inner arm i thereof, thereby raising the rack litter and bringing the lifting shoes 108 into engagement with the carriage rock, the said lifting shoes swinginq' the latter upward out of enqagement with the feed pinion 25, thus releasing or freeing the carriage from its es- .icapement devices and permitting it to be drawn continuously and rapidly leftward by the carriage unpelhng means or spring drum.

is has been said t d bl h h l ,11ses1rae,\vente curl-rage 1S released from its eseapement devices and 1s moved continuously a greater or less dlstuncc under the pull of the spring drum, to render the longitudinal ribbon feed- 2 mg mechamsm inoperative during such contmuous movements of the carriage.

In the present instance this disconnection of the j ribbon is preferably accomplished by means comprising a disconnect' or releasing member which is illustrated iii l igs. 2, 3, 4, 5 and 7 being most clearly shown :11 the last mentioned figure. The switching or disconnectmg member is des' nated as a whole by the numeral 109 and is preferably formed of sheetmetal cut out and bent to the desired shape. The member comprises a body portion 1 10 having at its outer or right-hand end aresrwardly bent extension 111, said extenslon underlyin the right-hand arm of the lever 101 and be" a formed with oppositely disposed inclined aces 112 and 113 and a central dwell 114 which is somewhat wider than the thickness of the righthand arm of the lever 101 near its outer end. The inner or left-hand end portion of the body of the switching or disconnecting member 109 is bent downwardl at right angles as indicated at 115 to avoid the block or 1 73 and thence inwardly again or toward t 0 left under the lug 73 as indicated at 116, the end of the part 116 being joined by an extension 117 extending forwardl lengthwise of the detentarm 71 and at rig t angles to the part 116 and to the body 110. Headed screws 118 pass through openings in the extension 117 and engage with t readed openings in the right-hand face of the detent arm 71, said screws thereby securing the number 109 fixedly to said doteut arm. The member 109 is in cfiect a part of the vibratory detent member or device comprising the arm 71 and the extension 70, said member 109 being adapted to turn member on the 1 From a consideration of these last mentioned figures it will be noted that the leftward longitudinal movement of the driving shaft has been sufficient to disconnect the right-hand driving )inion 55 from its associate pinion 54. but has not been sullicient to 1 cause an engagementbetween the left-hand driving pinion 55 with its associate pinion 54. In other words, the driving shaft has been the ribbon driving shaft 56 is ositioned as shifted to an inoperative position so that it shown in Figs. 4 and 5, the rig it-hand drivg is entirely disconnected from the ribbon ing pinion 55 on said shaftwill be enga ed spools and neither of its pnnons 55 is in opwith its associate pinion 54 on the rig erative enga emcnt. As will be understood hand shaft 52 and during the letter space from a consi oration of Fig. 12, the leftward feeding movements of the carriage the ribbon T movement of the detent arm 71 has not been will be wound on the right -hand ribbon sullicient to carry the roller 74 out of enspool and drawn off or unwound from the gagenientwith the notch 75, the result being left-hand rihbon spool. At. this time the t that the pressure of the spring 80 is exerts detent arm 71 and the switching or disconthrough tic cam plate 77 on the roller 74 and necting member 109 will be in the position with said vibratory detent pin 72 as a center and being connected by said vibrator detent member with the rib- 1 bon driving s aft 56.

The switching or disconnecting mend-er 109 is adaptei'l to be automatically operated by the releasing lever 101 when the tabulating key 81 is depressed, as will he more clearly understood fromwhatfollows. \i'he-n from it is transmitted through the arm 71 to shown in Figs. 4 and 5 and the extension 111 E the driving shaft 56 to restore said driving will be positioned relatively to the outer end shaft to the position shonn in Fig. 5 whenortion of the right-hand arm of the rcleasever pressure on the tabulsting key 81 is reing lever 101 as most clearly indicated in moved. From what has been said it will be Fig. 8. Vi'ith the parts thus positioned, if aipparent that when the means for releasing the tahulating key 81 be depressed it will t c carria 'e from its escapement device is operate as has been described to turn the operated flie ribbon and ribbon spools are column stops to operative position and to reautomatically disconnected from the carri e lease or free the carriage from its esc-apeimpelling means and the longitudinal ri ment devices, this latter operation being bon feeding mechanism is automatically reneflected throu 1 the releasing lever 101, the dered inoperative, and that, thereafter by outer or rightand arm whereof is depressed means of the spring 80 said ribbon feeding by the finger 100 and the left-hand arm i means is again rendered operative automatwhereof is raised about the fulcrum 102.

This results in a forward moveeline 112. -\s the detent arm 71 is swung Z ment of the extension 111 of the member leftward about the pin 72 under the act-ion 109 and brings the inclined face 113 of of the lever 101, the notched extension said extension under the outer portion of the engaging the left-side of the circumferential ri ht arm of the lever 101 as illustrated in groove 69 in the driving shaft 56, will force 2 Fig. 10 and in the dotted line position of said driving shaft longitudinally leftward, 5. From a consideration of these figures it com ressing the sp 80 and forcing the 5 will be understood that when the tabulating notc ed head rearward y, the roller 74 rldin key is operated, the lever 101 will cooperate leftward over the left-hand face of the note with the inclined face 113 to press the shift- 75 in said head 77.

It will be seen, therefore, that the automatic ribbon disconnecting means is operative in either of the shaft as is the automatic reconnecting mechanism. The construction is such that when the tabulator key is de ressed the driving shaft will be automatically discoimected from whichever one of the ribbon spools it happens to be connected with at the time;

When the tnbulat-or key is depressed the inclines U2 and 113 cause a rearward and forward ressure respectively on the lever 101. In or er to revent deflection of said lever suitable guic es therefor may be provided if preferred.
